Weld allows for concurrent call to conversation

Concurrent calls to a @ConversationScoped component:

Thread 1:

AbstractConversationContext.activate(String cid)
ConversationImpl.lock(long timeout) <-- returns true

correctly proceed inside method

Thread 2:

AbstractConversationContext.activate(String cid)
ConversationImpl.lock(long timeout) <-- returns false but activate() does not check result !!!

incorrectly proceed inside method

I think AbstractConversationContext.activate(String cid) should check the result of ConversationImpl.lock(long timeout) and not allow the second thread to proceed.
